NullStateStore

Dummy state store implementation that doesn’t do anything.

Inherits: IStateStore

It can be used in testing or in situations when state management is not required but shall be disabled.

Deletes a state from the store by its key.

public Task<T> DeleteAsync<T>(IContext context, string key)

context: IContext - (optional) a context to trace execution through a call chain.
key: string - a unique value key.
return: Task<T> - removed item

Loads state from the store using its key. If value is missing in the store it returns null.

public Task<T> LoadAsync<T>(IContext context, string key)

context: IContext - (optional) a context to trace execution through a call chain.
key: string - a unique state key.
return: Task<T> - the state value or null if value wasn’t found.

Loads an array of states from the store using their keys.

public Task<List<StateValue<T>>> LoadBulkAsync<T>(IContext context, List<string> keys)

context: IContext - (optional) a context to trace execution through a call chain.
keys: List<string> - unique state keys.
returns: Task<List<StateValue<T>>> - an array with state values and their corresponding keys.

Saves state into the store.

public Task<T> SaveAsync<T>(IContext context, string key, T value)

context: IContext - (optional) a context to trace execution through a call chain.
key: string - a unique state key.
value: T - a state value.
returns: Task<T> - execution duration in milliseconds.
